[0002] In the process of tire assembly and production, in order to save the space occupied by automobile tires, automobile tires are generally stacked and piled up to fully utilize the production space and realize the purpose of rapid transportation and transfer. However, based on the prior art, it is found that in the existing tire stacking equipment, the mechanical claw will clamp the tire from the outside of the tire when grabbing the tire, which results in the mechanical claw needing to use a larger clamping force to clamp the tire in the process of clamping the tire, and then transfer the tire, which is easy to cause the tire to be deformed by greater pressure, and in the process of stacking tires, when the mechanical claw releases the tire, the tire will rebound and catapulted to another adjacent tire that has been stacked, which causes the entire set of tires that have been stacked to shake easily, resulting in an increased risk of collapse of the stacked tires; Moreover, when the stacked set of tires is transported, necessary protective measures are lacking, which may easily lead to the unstable center of gravity of the whole set of tires during the transport, further increasing the risk of collapse.

[0026] A rubber strip is provided on the upper surface of the push rod 213 to increase the friction between the push rod 213 and the tire 6 and prevent the push rod 213 from scratching the tire 6 .

[0028] When the vertical tire automatic stacking equipment is in use, the image recognition device installed at the lower part of the fixed plate 204 is used to identify the tire 6 in the area, so as to determine the location of the tire 6, and then the two second electric sliders 2 are controlled to start moving along a second electric slide rail 1 according to the location of the tire 6, and the movement of the two second electric sliders 2 drives the third electric slide rail 3 to move, and then drives all the connected parts to move, and then the two third electric sliders 4 are controlled to start moving along the third electric slide rail 3, and the movement of the two third electric sliders 4 drives the support frame 5 to move, and the movement of the support frame 5 drives all the connected parts to move, and then drives all the swing rods 208 to move, so that all the swing rods 208 move to the position just above the tire 6, and the center of the connecting rod 205 is aligned with the center of the tire 6, and then the two second electric actuators 202 are controlled to start and drive each fixing ring 203 to move downward, and the movement of the two fixing rings 203 drives the fixing plate 204 to move, and the movement of the fixing plate 204 drives the connecting rod 205 to move, and then drives all the connected parts to move, and then drives all the swing rods 208 to move to the inner side of the tire 6, as shown in FIG. Figure 5As shown, the two first electric actuators 207 are controlled to start and drive the sliding block 2071 to move downward, and the sliding block 2071 moves through the corresponding inclined rod 2072 to drive the corresponding swing rod 208 to move, so that all the swing rods 208 expand outward, and then drive the connected fixed block 209, the rotating shaft 210, the fixed rod 211, the elastic member 212 and the top rod 213 to expand outward, and make the top rod 213 move close to the inner side wall of the tire 6, so that the distance between the two opposite top rods 213 on the left and right and the distance between the two opposite top rods 213 on the front and back are greater than the diameter of the upper opening of the tire 6, so that the four top rods 213 can support and limit the tire 6 from the inner top of the tire 6; after the four top rods 213 are all expanded outward, the two second electric actuators 202 are controlled to start each driving A fixing ring 203 moves upward, and the movement of the two fixing rings 203 drives the fixing plate 204 to move, and the movement of the fixing plate 204 drives the connecting rod 205 to move, thereby driving all the connected parts to move, thereby driving the four top rods 213 to move, and making the four top rods 213 move upward to press against the inner top of the tire 6. At this time, the four top rods 213 all rotate, thereby driving the corresponding fixing rods 211 to rotate, and then twisting the four elastic members 212, so that the tire 6 is supported and limited from the inner top of the tire 6 by the four top rods 213, thereby avoiding squeezing of the tire 6 and causing the tire 6 to deform. Then, the two second electric actuators 202 are controlled to start in the same way as above, and then the two second electric sliders 2 are controlled to start, and the two third electric sliders 4 are controlled to start, so as to move the tire 6 to the specified position.

[0029] After the tire 6 is moved to the specified position, the four push rods 213 are separated from the inner top of the tire 6, and the two second electric actuators 202 are controlled to start and each drive a fixing ring 203 to move downward, the two fixing rings 203 move to drive the fixing plate 204 to move, the fixing plate 204 moves to drive the connecting rod 205 to move, and then drive all the connected components to move, and then drive the four push rods 213 to move downward and separate from the inner top of the tire 6, and then control the two first electric actuators 207 to start and drive the sliding block 2071 to move upward, the sliding block 2071 moves through the corresponding inclined rod 2072 to drive the corresponding swing rod 208 to move, so that all the swing rods 208 shrink inward, and then drive the connected fixing block 209, the rotating shaft 210, the fixing rod 211, the elastic member 212 and the push rod 213 to shrink inward and reset, and then control the two second electric actuators 202 to start and each drive a fixing ring 203 to move upward in the same way as above, so that all the swing rods 208 move upward and separate from the tire 6.

[0030] When palletizing, all the swing rods 208 are moved in the same manner as described above, and then the four top rods 213 support and limit another tire 6, and then drive the other tire 6 to move until the two tires 6 are stacked and palletized. Figure 5 As shown, when multiple tires 6 need to be stacked, the tires 6 are continuously stacked upward in the same manner, thereby achieving automatic stacking of the tires 6 .

[0031] Embodiment 2: Based on the first embodiment, according to Figure 1 and Figure 6-Figure 7 As shown, it also includes a stacking system; the stacking system is connected to the support frame 5; the stacking system includes a fourth electric slide rail 301, a fourth electric slider 302, a third electric actuator 303, an arc rod 304, a sleeve 305 and a limiting roller 306; two fourth electric slide rails 301 are fixedly connected to the support frame 5; each fourth electric slide rail 301 is slidably connected to a fourth electric slider 302; each fourth electric slider 302 is fixedly connected to a third electric actuator 303, the third electric actuator 303 is an electric push rod, and each telescopic part of the third electric actuator 303 is fixedly connected to a arc rod 304; each arc rod 304 is fixedly connected to two sleeves 305; each sleeve 305 is rotatably connected to a limiting roller 306.

[0032] A pressure sensor is provided at the connection between the third electric actuator 303 and the arc rod 304 for detecting the pressure exerted on the limiting roller 306 when limiting the tire 6 .

[0033] The upper end of the limiting roller 306 and the lower end of the limiting roller 306 are both provided with a hemispherical protrusion for preventing the tire 6 from being scratched.

[0034] The outer surface of the limiting roller 306 is made of smooth stainless steel to prevent the tire 6 from being scratched.

[0035] It also includes a first electric slide rail 51 and a first electric slider 52 ; the first electric slide rail 51 is fixedly connected to the support frame 5 ; the first electric slider 52 is slidably connected to the first electric slide rail 51 ; the first electric slider 52 is fixedly connected to the mounting plate 201 .

[0036] In the process of continuously stacking tires 6, the overall height of the stacked tires 6 will continue to increase, thereby making the center of gravity of the tires 6 stacked on top unstable. If the tires 6 are continuously stacked upward, all the stacked tires 6 will collapse, thereby affecting the normal stacking. To solve the above problem, when two tires 6 are stacked, the two fourth electric sliders 302 are controlled to start and move downward along a fourth electric slide rail 301. The movement of the two fourth electric sliders 302 each drives a third electric actuator 303 to move. The movement of the two third electric actuators 303 drives all the connected components to move, thereby making the corresponding limit The rollers 306 all move downward and are located on the outer side of the lowest tire 6. Then, the two third electric actuators 303 are controlled to start and drive each arc rod 304 to move. The two arc rods 304 move the corresponding sleeves 305 and the corresponding limiting rollers 306 until the corresponding limiting rollers 306 all press against the outer side of the lowest tire 6. Thus, the tire 6 is limited by the corresponding limiting rollers 306. The outer diameter of the tire 6 and the placement position of the tire 6 can be known through the corresponding limiting rollers 306. At this time, the position of the corresponding limiting rollers 306 remains unchanged, so as to facilitate the limiting and correcting of the tires 6 to be stacked subsequently. Then, the two fourth electric sliders 302 are controlled to start and move upward along a fourth electric slide rail 301 respectively. The movement of the two fourth electric sliders 302 drives all the connected parts to move, and then drives the corresponding limiting rollers 306 to move upward. Since the corresponding limiting rollers 306 have limited the bottom tire 6, and the position of the corresponding limiting rollers 306 remains unchanged, the corresponding limiting rollers 306 can limit the upper tire 6 when moving upward, and if the upper tire 6 is not aligned with the lower tire 6, the upper tire 6 can be squeezed by the corresponding limiting rollers 306, thereby forcing the upper tire 6 to remain flush with the lower tire 6. Figure 7 As shown, the stacked tires 6 are kept flat as a whole, reducing the risk of collapse; When the tires 6 are continuously stacked upward, the position of the corresponding limiting roller 306 remains unchanged and is located between the two tires 6 that have been stacked. Figure 7As shown, the swing rod 208 has been separated from the tire 6 located above, and then the first electric slider 52 is controlled to start moving along the first electric slide rail 51. The movement of the first electric slider 52 drives the installation plate 201 to move. The movement of the installation plate 201 drives the two second electric actuators 202 to move. The movement of the two second electric actuators 202 drives all the connected parts to move, and then drives all the swing rods 208 and all the connected parts to move. Then, the remaining tires 6 are limited in turn by the four top rods 213, and the tires 6 are stacked and palletized in turn. Since the two tires 6 located at the bottom are limited by the corresponding limiting rollers 306, the stacked tires 6 can be kept stable as a whole when the tires 6 are continuously stacked and palletized upward. As more and more tires 6 are stacked and palletized upward, the two fourth electric sliders 302 are controlled in the same way as above to start moving upward along a fourth electric slide rail 301, so that the corresponding limiting rollers 306 move upward step by step until all the tires 6 are limited in turn, so that all the tires 6 are kept flush. It should be noted that in the prior art, a mechanical claw is used to clamp the tire 6 from the outside of the tire 6, which results in the mechanical claw needing to use a larger clamping force to clamp the tire 6 and then transfer the tire 6. However, the present device uses a connecting rod 205 to bear the weight of the tire 6, and then limits the tire 6 through a limiting roller 306 to prevent the tire 6 from being transferred in a tilted manner, thereby avoiding deformation of the tire 6 that affects its quality.

[0037] After stacking multiple tires 6, all the stacked tires 6 are transferred at once. At this time, all the swing rods 208 are moved to the inner side of the lowest tire 6 in the same way as above, and the four top rods 213 are pressed against the inner top of the lowest tire 6, so as to support and limit the lowest tire 6. At the same time, the corresponding limiting rollers 306 move upward step by step until all the tires 6 are limited in turn, so that the corresponding limiting rollers 306 are located between the two uppermost tires 6, and the two uppermost tires 6 are limited. Then, the two third electric actuators 303 are controlled to start and each drives an arc rod 304 to move, so that the two arc rods 304 move toward each other, so as to make The corresponding limiting rollers 306 move toward each other to apply pressure to the two tires 6 at the top, thereby increasing the friction between the corresponding limiting rollers 306 and the two tires 6 at the top, and then control the two fourth electric sliders 302 to start and move downward along a fourth electric slide rail 301, thereby driving the corresponding limiting rollers 306 to move downward, so that the two tires 6 at the top jointly apply pressure to the remaining tires 6, and the tire 6 at the bottom has been supported and limited by the four top rods 213, so that all the tires 6 that have been stacked form a whole and then are transferred, thereby avoiding the problem of skewing and collapse of all the tires 6 that have been stacked during the transfer process, thereby completing the stacking and transfer operations of all the tires 6.

[0038] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
